Phosgene, also known as carbonyl chloride, chemical formula for COCl2, at room temperature has rotting grass taste, colorless and highly toxic.The phosgene is unstable in chemical properties and hydrolyzed rapidly in water to form hydrogen chloride.
Nitric oxide is a colorless and odorless toxic gas at room temperature.Because nitric oxide contains free radicals that make it very reactive, it is easily oxidized in air to form the corrosive gas nitrogen dioxide
Nitrogen dioxide (chemical formula: NO2) is a reddish-brown, pungent odor of harmful gas, easy to dissolve in water, and the formation of nitric acid.
Sulfur dioxide (chemical formula SO2) is a colorless gas with a strong pungent odor, is one of the main pollutants in the atmosphere.Sulfur dioxide in air pollution mainly comes from the combustion of sulfur compounds in coal and petroleum.
Ozone (chemical formula: O3) is a kind of light blue gas with a special odor, slightly soluble in water, very unstable at room temperature, and easy to decompose into oxygen. Ozone is useful, but not completely harmless, when its concentration in the air is high, it will cause damage to human beings, animals, and plants.
Silane is a group of silane organic compounds, including methyl silane (SiH4), ethyl silane (Si2H6) and some isomeric or higher alkanes.One of the most commonly used is methylsilane, so commonly referred to as nail silane.
Tetrahydrothiophene (chemical formula: C4H8S) at room temperature is a volatile liquid without color, very low levels in the air when you can smell, and the gas equipment, pipeline gasket material such as corrosion
Chlorine dioxide is a yellowish-green to orange-yellow non-toxic gas. It is the most stable oxide of chlorine and the only halogen oxide produced in large quantities.As an extremely powerful and effective oxidant, chlorine dioxide is mainly used in the disinfection of tap water and bleaching of flour and wood pulp.
